Abstract:
An FRP roof material which eliminates the possibility of occurrence of rusting, can provide a light weight and sufficiently high strength and rigidity, can deliver a high insulating feature, can contribute to an increase in earthquake-resistance of a building, and also can be formed in any highly attractive shape easily, characterized by comprising a sandwiched structural body in which a pair of plates (3a, 3b) made of FRP are disposed at an interval and rib structural bodies (4) connecting the pair of plates to each other are provided between them, wherein, when phenol resin is used as FRP matrix resin or refractory material is provided on the surface of the roof material, the roof material excellent also in fire resistance can be obtained and, in addition, when end parts of the material are butted against each other for connection, a resin diffusing medium is disposed between butted end faces, reinforcing fibers are disposed over the entire surface of both end face parts, and resin is filled into the resin diffusing medium so that the resin can be diffused to the reinforcing parts to assure connection.
Abstract:
A container especially ideal for storage in aircraft has wall-defining members providing side walls, a roof and a base. At least the side walls are provided by FRP sheet material having a thickness, t(mm), given by 0.3 ≤ t ≤ 1.5 and a fibre content, Vf(%), given by 25 ≤ Vf ≤ 65.
Abstract:
The present invention relates to a joint structure for an FRP roofing member wherein two or more FRP sandwich structures are butt joined, an FRP connecting layer extends across the surfaces of both ends of the sandwich structures, and a layer containing a resin distribution medium is provided between the abutting end faces. The present invention also relates to a method for joining FRP roofing members. In accordance with the FRP roofing member joint construction of the present invention, the problems associated with conventional joint structures can be completely overcome, and the ends of the sandwich structures can be easily, firmly and cheaply joined together. As well as ensuring high joint strength and rigidity, an excellent appearance can be achieved.

PROBLEM TO BE SOLVED: To provide an FRP cylindrical form with high tensile and compression strength consisting of a tapered part which tapers off to one of the ends of a cylinder and a large diameter part which is connected to the tapered part, provided on the end of the FRP cylindrical form in such a manner that the large diameter parts is arranged within a specific range in the cylindrical shaft direction, and further, a reinforcing fiber layer containing reinforcing fiber which accounts for a specific percentage of the total reinforcing fiber volume and another reinforcing fiber layer arranged outside the former reinforcing fiber layer. SOLUTION: The pipe center part 6 of an FRP cylindrical form 1 consists of a reinforcing fiber layer 3 and a reinforcing fiber layer 4, and a reinforcing fiber layer 5 containing reinforcing fiber arranged within an area of ±30 to ±55 deg. with a pipe shaft direction, is interposed between the reinforcing fiber layers 3, 4. In addition, on account of the formation of the reinforcing fiber layer 5, a tapered part 7 which tapers off to the end of the pipe from the pipe center part 6, enlarging the diameter is formed the pipe end part, and a large diameter part 8 which extends in the form of a straight pipe from the tapered part 7 to the pipe end is formed. Besides, the percentage of the reinforcing fiber container in the reinforcing fiber layer 5 of the large diameter part 8 is adjusted to the range of 25-50% of the total reinforcing fiber volume.

PURPOSE: To enhance the strength of a joining area by fitting an insert jig into an FRP pipe, and providing a groove area in a fit-in surface of this insert jig, and filling a filler into the groove. CONSTITUTION: A metal-made insert jig 2 is fitted into an FRP pipe 1 on both sides of the FRP pipe 1 where a groove area 3, which is designed to fill up a filler 6 into the jig 2, is formed on the whole periphery of the insert jig 2. An O ring 4, which closes the fit-in surface between the FRP pipe 1 and the jig 2 is installed before and behind the grove area 3 of the insert jig 3, thereby laminating a reinforcing layer 5 on the outer peripheral surface of the FRP pipe 1 in the fit-in part between the FRP pipe 1 and the insert jig 2. It is, therefore, possible to broaden the application range of the FRP pipe connector since the strength of the connecting area is high and heat resistance is also enhanced.

PROBLEM TO BE SOLVED: To provide a lightweight winding type opening-closing roof with a simple composition and lesser number of components. SOLUTION: This winding type opening-closing roof 10 is provided with a plurality of travel passage beams 20 arranged in parallel, roof panels 30 laid between the travel passage beams and capable of moving along the travel passage beams, and a winding drum 50 winding the roof panels along the travel passage beams. The roof panel has a flexible portion 32 composed of a thin plate 37 having water cut-off ability, and reinforcing portions 34 having a predetermined strength attached to the thin plate. The reinforcing portions are attached to indoor and outdoor sides of the thin plate so as to perpendicularly cross the travel passage beams.
Abstract:
PURPOSE:To provide a tubular element which has high rigidity, made of FRP, and a manufacturing method thereof by forming a rubber covering layer cured by hot water on its surface. CONSTITUTION:This tubular element, which is an FRP tubular element 1 where the covering layer of vulcanized rubber cured by hot ster is formed on an outside surface 1a, is provided with a layer 3 which has poorer absorption than the tubular element 1 or non-absorption properties at its inside surface 1b. This layer is formed at the time of forming the FRP tubular element or after forming it. Then the rubber covering layer is formed on the outside surface of the tubular element by hot ster curing to manufacture this tubular element.
